' CONVEYER-CHAIN.

Application filed March 22, 1911.

novel construction of chain which shalladapt it for use moreparticularly in bottlecleansing machines to form the conveyer equippedwith pockets at intervals for holding bottles to be cleaned. I haveespecially devised my improvement for the endless conveyor in thebottle-washing machine which forms the subject of the pendingapplication for Letters Patent of George W. Dobson, Serial No. 601,572,filed January 9, 1911.

In the accompanying drawing, Figure 1 is a broken plan view showing asection of my improved chain illustrating its construction and use as apocket-equipped conveyer supported to travel on a track; Fig. 2 is asection on line 2, Fig. 1; Fig. 3 illustrates a broken portion of thechain showing by an outer face view one of the two varieties of linksemployed in its construction; Fig. 4 is a similar view of the sameshowing the inner face of the link, and Fig. 5 is a broken view inelevation of one of the bottle-pockets as adapted to have the aforesaidlink of Figs. 3 and 4 fastened to it.

The chain is composed of two varieties of links, 5 and 6, formed ofdifferent metals to avoid, more particularly, necessity for lubricatingtheir joints, the links 5 being solid and preferably cast of brass orbronze and the links 6 being preferably steel. Each link 6 comprises twobars 7 7 both prefer-- ably alike and stamped out of steel in the shapeillustrated, with eyes 8 in their rounded and expanded ends. Each link 5is a casting formed with hollow cylindrical heads 9 on its endsconnected by a web 10 having a flat side 11 and an angular Web 12 on itsouter side forming a socket 13 of general T-shape, for the purposehereinafter stated, containing a central bolt-hole 14; and on the innerface of the web is formed, to extend centrally from it at a right-angle,a lug 15 having a protuberance 16 formed on its face, the lug containinga rivet-hole 17 The links are connected together by pivot-pins 18 whichare passed Specification of Letters Patent.

through the eyes provided in their lapping ends to receive them, and theprojecting ends of the pins may be riveted, as shown.

For the purpose of illustrating the use of my improved chain as aconveyor for the purpose set forth in the aforesaid application, it isrepresented in Figs. 1 and 2 to be supported on one rail 19 of a trackto travel thereon, the companion track-rail 20 sup porting holders orpockets, one being shown at 21 fastened to the chain, which carries themat intervals throughout its length. The shape of the pocket illustratedconforms, at least approximately, to the shoulder and neck portions of abottle to be supported in it in inverted position; but it may be of anyother suitable shape and general construction. It is provided on oneside with a shoe 22 to rest on and guide the pocket along the rail 20.Diametrically opposite the shoe, at a recess 23 in the inner wall of thepocket is formed on its outer wall a protuberance 24 containingrivetholes 14 and 17 respectively near its opposite ends and, betweenthe latter, a recess 25. The outer face of the protuberance 24 is thereverse of that of the opposing face of the lug 15 and part of the web10 from which it extends, whereby they fit against each other, formingjointmembers, with the protuberance 16 entering the recess 25 to stablyjoin the pocket to a link 5, to Which the pocket is securely fastened asby rivets 26 and 27 passing, respectively, through the coincident holes14, 14 and 17, 17 with their inner heads Within the recess 23 to preventtheir being encountered by and breaking a bottle introduced into thepocket and with the outer head of the rivet 27 housed in the link-recess13.

The chain thus described, besides presenting the advantage referred tobecause of the different metals composing successive links, is renderedpeculiarly strong and durable, for its conveyer-purpose referred to, byreason of the ribbed construction of the links 5; and the provision onthe latter of the lug-devices as companions for the recessedprotuberances 24 on the pockets for the union of the latter with thoselinks, affords very strong and stable junction between them capable ofeflectually resisting wear and disorganization of the parts under thegreat strains to which the conveyer is subjected in use.

What I claim as new and desire to secure by Letters Patent is 1. Aconveyer-chain having each of its alternate links formed of a pair ofbars, and solid intermediate links each composed of a web havingend-heads and ribs on one side with a lug on its opposite side, for thepurpose set forth.

In combination, a chain having each of its alternate links formed of apair of bars and solid intermediate links each composed of a web havingend-heads and a lug extending from one side with a protuberance on itsface, and bottle-holders each provided on its outer wall with aprotuberance containing a recess and interfitting with and secured toone of said link-lugs.

3. In combination, a chain having its alternate links formed of pairs ofbars and the intermediate links solid and each composed of a web havingend-heads and ribs on one side with a lug on its opposite side providedwith a protuberance'and forming a joint-member, and bottle-holders, eachprovided with a recess in its inner wall and a protuberance forming ajoint-member coincident with said recess on its outer Wall andcontaining a recess, said link and holder joint-members interfitting andbeing pinned together with the inner heads of the pins in saidpocket-recesses.
